Re: if vs. ifdef in Makefile.am

Hi,


I observed that it adds `NDEBUG` in `config.h`. I will need to include this `config.h`, right?


// config.h
#define NDEBUG 1



My current solution is like the following. I do not know if it can be simplified.


# src/configure.ac
AC_ARG_ENABLE(
    [ndebug],
    [AS_HELP_STRING([--enable-ndebug],
        [ndebug means release and turns off assert])],
    [enable_ndebug=yes]
)


AM_CONDITIONAL([NDEBUG], [test x$enable_ndebug = xyes]) 


---


# src/main/Makefile.am
if NDEBUG
CPPFLAGS += -DNDEBUG
CFLAGS += -O3 # .cpp
else
CFLAGS += -g # .cpp
LDFLAGS += -fsanitize=address
endif



---


// src/main/main.c


void handlerCont(int signum){
  printf("SIGCONT %d\n", signum);
#ifndef NDEBUG
  __lsan_do_recoverable_leak_check();
#endif
}
